Now that is a very good and valid question..
Looks like a real lot of stock is already owned based on the A/D line. People judge risk, maybe they already own what they feel comfortable with until news comes out.
If you are not a believer (not just you , anyone) and sold or hate it here, then one strategy is to wait til news comes out and know how to chase it and where it might land. That takes a lot of risk out of it. Even if you paid 5 or even 10 ticks higher in the long run if it goes way up at least you didnt take a chance before news and limited to the downside risk.
Everything I post is my own opinion and people should always do their own research and due diligence on any company they are looking at
